DIP Switch Settings
There is a bank of DIP switches on the top edge of the PC board. The drain frequency and duration
(drain time) and the Service Life time setting can be modified (please consult factory prior to
changing Service Life time). Several other parameters are also adjustable. The main power must be
turned off before the DIP switches are changed. See chart below for a complete listing
of DIP
switch settings. Please consult factory if unsure regarding any DIP switch setting. See Fig.
9-1 for locations.
